Seems that this might be the Hyatt’s summer promotion this year. 1,500 miles per stay (500 base + 1,000 bonus) is not bad for cheap stays, but makes very little sense for expensive ones.

Here are the terms and conditions of this Air France-KLM offer:

ELIGIBILITY/HOW TO REGISTER: To be eligible to participate in this Promotion, you must be a member of Hyatt Gold Passport and a member of AIR FRANCE KLM Flying Blue. To register for this promotion, visit hyatt.com/airfrances14 or by calling 1-800-228-3360 and request enrollment code AF14S. Void where prohibited.

ELIGIBLE STAYS: For the purpose of this Offer, an “Eligible Stay” is defined in the complete Terms and Conditions of the Hyatt Gold Passport program, except that stays at M life resorts do not count as Eligible Stays under this promotion. Hyatt Gold Passport members will only receive Eligible Stay credit for their room, regardless of the number of paid rooms.

HOW TO PARTICIPATE: To receive bonus Miles you must register for this promotion, provide your Hyatt Gold Passport and AIR FRANCE KLM Flying Blue member number at check-in, be a registered guest physically occupying the room to which you are registered, and choose AIR FRANCE KLM Flying Blue Miles for your stay. During the Promotion Period, complete two (2) Eligible Stays at any participating Park Hyatt®, Andaz®, Grand Hyatt®, Hyatt Regency®, Hyatt®, Hyatt Place®, Hyatt House®, Hyatt Ziva™, Hyatt Zilara™ or Hyatt Residence Club® hotel and resort worldwide. Beginning with your second Eligible Stay, you will earn 1000 bonus Flying Blue Miles for every Eligible Stay, up to your fifteenth (15) Eligible Stay. Bonus Miles are not awarded on your first Eligible Stay so you can earn bonus Miles on up to fourteen Eligible Stays. Bonus Miles are awarded in addition to the 500 base Miles you can earn for each Eligible Stay. These Miles are cumulative. A maximum of 7,500 base Flying Blue Miles and 14,000 bonus Flying Blue Miles may be earned during Promotion Period.
